Hi all

I need to run MyFunction.m tomorrow starting from 14:20:00 and repeat it 10 times with periodicity of 5 minutes. How to proceed?

Thanks for help

MATLAB does not support that.

The closest to that is that timer supports a start delay -- so you could calculate the time difference between now and 14:20 tomorrow and use that as the delay. But that is going to not going to start exactly on time -- and if you exit MATLAB in the meantime then the timer will not run, and will not start up again if you go back into MATLAB.

I would suggest writing a control table to a file indicating the date/time when each event is to start.

Then, periodically:

read the file
schedule a timer object (using relative time) for any event that is due to start within the next two refresh cycles; if there is already a timer for the event, check to see whether the start time delay needs to be updated

This scheduling should also be done upon starting MATLAB

Creation of a new event should be accompanied by writing the event to the control file and then running the check cycle again.
